D23-LB LoRaWAN 3-Channel Temperature Sensor Node 868Mhz

The D23-LB by Dragino is an 868Mhz waterproof LoRaWAN sensor node with three temperature sensors. The DS18B20 temperature sensors used measure in a range of -55°C to 125°C with a tolerance of ±0.5°C (max ±2.0°C). The module has a 1.5m sensor cable attached, which terminates in three separate temperature probes. This robust sensor node, packed in a weatherproof housing, is ideal for outdoor use and is powered by an 8500mA Li/SOCl2 battery, ensuring a long operating life. The D23-LB is more than just a sensor node. It was designed to facilitate the quick implementation of industrial LoRa and IoT solutions. The wireless part of the node is based on the SX1262, allowing for data transmission over very long distances at low data rates. This ensures exceptionally wide range, high interference resistance and optimized power consumption. Equipped with a powerful 48 MHz ARM microcontroller, 256KB flash and 64KB RAM, the PS-LB-NA is ready for all kinds of projects. The D23-LB has an integrated BLE module, which allows for convenient configuration of the sensor from your mobile phone. It also supports OTA updates via a private LoRa protocol, significantly simplifying maintenance. This sensor node is the third generation of the popular LSN50V2-D23 from Dragino and offers a mature LoRaWAN stack as well as application software. You can use the pre-installed software for your IoT projects or adapt the software flexibly to different requirements. 

Each sensor comes preloaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server, and the sensor automatically connects after being powered up if network coverage is available.
